As for today Wireless Mesh Networks (WMNs) is emerging technology due to their rapid deployment. WMNs are dynamically self-organizing, self-configuring and self-healing with the nodes in the network automatically establishing an ad hoc network and maintaining the mesh connectivity. In order to Design a routing protocol for WMNs requires several criteria to be taken into consideration, such as w...

QoS (Quality of Service) aware spectrum sensing and channel allocation in cognitive radio wireless mesh networks is a continuous practice due to the divergent scope of communication in wireless mesh networks. Henceforth the current research is moving in a direction to find effective solutions towards QoS aware spectrum sensing and channel allocation. But all of these solutions are specific to o...

IEEE 802.11s wireless LAN mesh network technology is the next step in the evolution of wireless architecture. A WLAN mesh network consists of WLAN devices with relay functions that communicate directly. In this type of networks, path selection is based on two protocols: HWMP and RA-OLSR. This paper presents a detailed study of the performance of the proposed path selection algorithms for IEEE 8...

Multi-hop wireless mesh network experience link-failure due to channel interference, dynamic obstacles etc. which causes performance degradation of the network in Wireless Mesh Networks. The paper proposes “Autonomously Reconfigurable Wireless Mesh Networks system based upon IEEE 802.11” for mr-WMN to recover autonomously in case the network failure occurs, to improve the network performance. T...

The demands for the network usage are increasing day by day. During their lifetime, multihop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles, and/or applications’ bandwidth demands, which may degrade the system performance. This paper presents an autonomous network reconfiguration system (ANRS) that enables a multiradio WMN to au...

Wireless mesh networks have seen a real progress due of their implementation at a low cost. They present one of Next Generation Networks technologies and can serve as home, companies and universities networks. In this paper, we propose and discuss a new multi-objective model for nodes deployment optimization in Multi-Radio Multi-Channel Wireless Mesh Networks. We exploit the trade-off between n...

Wireless mesh networks provide cost-efficient means to ubiquitous Internet access. Large-scale wireless mesh networks may use multiple access networks. Depending on the routing protocol, a node may not know over which of these access networks it is communicating. In this report, we propose a routing protocol-independent method that allows nodes to (i) determine when they are switching the acces...

Multicast routing for wireless mesh networks has focused on metrics that estimate link quality to maximize throughput. Nodes must collaborate in order to compute the path metric and forward data. The assumption that all nodes are honest and behave correctly during metric computation, propagation, and aggregation, as well as during data forwarding, leads to unexpected consequences in adversarial...

Currently deployed wireless mesh networks are based on 802.11, WiFi, technology, which is not efficient in multihop scenarios. We present a method, which emulates 802.16 mesh networks over 802.11 hardware. The method works by embedding 802.16 packets into 802.11 broadcast packets and padding the 802.11 broadcast payload, so that the broadcasts are aligned to 802.16 TDMA frame boundaries. The me...

Stealthy packet dropping is a suite of four attacks can be easily launched against multi hop wireless Mesh networks. The main threats that viol attacks. The major attack types of WMN are denial of service attack, impersonation attack and routing attack. All these attac threat on user privacy protection, once disclosed to the attackers access the public Internet in different roles and contexts f...
